"I’m looking only at duos that would be totally new to the Smash Bros. franchise. In order to for a duo to make my list today, they have to have not been playable in any of the Super Smash Bros. games – even characters who were dropped between Melee and Brawl. The other rule is that the two must be known as a duo – no haphazardly throwing characters together. The two characters must be known for their relationship to one another." - Joshua, BoomPopMedia
